Although the cast is heavily populated with ragamuffin children - and several dogs - the show manages not to succumb to sentimentality and instead delivers spectacle in spades.

As anyone who grew up with the film will tell you, the Child Catcher is a nightmare figure.

And now it's the turn of Richard "Rocky Horror" O'Brien to terrify a new generation, stalking around the stage like Nosferatu with a bad comb-over.

Michael Ball in disguise as a toy clown

O'Brien is just one of an impressive cast: Michael Ball is a likeable Caractacus Potts, the inventor extraordinaire who is struggling to raise his two kids with the help of their eccentric Grandpa (Anton Rodgers).

Rodgers steals many of the comic scenes, along with Brian Blessed and Nichola McAuliffe as the colourful despots of Vulgaria, Baron and Baroness Bomburst.

Blessed, in classic BlackAdder mode, is as hilarious and over-the-top as ever.

Cast in this ocean of seasoned talent, West End newcomer Emma Williams manages to keep her head well above water as Truly Scrumptious.

Cliff-hanger ending

Of course the car is the real star of the show - and it is mercifully not overused. There are times during the second act that you begin to wonder where it has gone.

Chitty Chitty Bang Bang's arrival on stage is breathtaking. And at the cliff-hanger ending to the first half, even though you know it is going to sprout wings, there is still a tingling down the spine.

Just how this production manages to make the car swoop over the stalls is pure mystery.

There's no mystery though about what happened to my beloved Chitty Chitty Bang Bang in the toy cupboard.

I gave it away to a jumble sale, where it would have sold for 10p. If anyone bought it - can I please have it back?
